Alarms and clearing alarms
Several alarms are registered and made available on modbus. Most of these are automatically cleared when the
error is no longer present. Sensor error : Temperature sensor error has a timeout of 10 minutes. This means that after
the reason for a sensor error has gone, the error will remain active for 10 minutes, and then it is cleared. for the
pressure sensor, the timeout is only 30 seconds.
There is an option to reset the errors externally by setting the 40075 (reset alarms) = 1.
